The package-lock.json file in npm is used for ensuring consistent installations of dependencies across different environments or for collaborative projects. package-lock.json is created for locking the dependency with the installed version. It will install the exact latest version of that package in your application and save it in package.json. In this article, we are going to learn whether there is any way to force NPM to generate package-lock.json or not.

Methods to Force Generation

1. Using –save

In this approach we are going to use this flag with npm that will install all dependencies required for your application and save in package.lock.json.

Syntax:

npm install --save

2. Using –save-dev

In this approach we are going to use this flag with npm that will install all dependencies required for your application and save in package.lock.json.

Syntax:

npm install --save-dev

3. Using install

In this approach all the other flags are deprecated by Node JS we can directly use npm to install dependencies and save in package.lock.json.

Syntax:

 npm install 

Example: In this GIF example first we deleted then Package-lock.json then we run the given command to install it.
